Installation with maxvz=0 leaves too much unused space in volume group "pve"

[Alexey Chernenkov]

I have two hard disks and I want to install Proxmox on the first disk and store all virtual machine data (disks/templates/etc) to the second one. So I set `maxvz=0` in the Proxmox installation wizard. After installation I have on the first hard disk:

• 1 PV /dev/sda3 PSize:200Gb PFree:100Gb
• 1 VG pve PSize:200Gb PFree:100Gb
• 2 LVs
  • root 50Gb
  • swap 50Gb

So, root volume uses only 25% of the total disk size, and VG pve uses only 50% of the entire disk. I think that this is a waste of space, because, I'm not going to create additional logical volumes in the VG pve. Could someone, please, advise me what to do with this free space? Is it ok, to extend root LV with all this free space?
